Suitability of recycled concrete aggregate for use in BS 5328 designated mixes
The results for the aggregate characteristics showed that plain as well as reinforced demolished concrete debris can be crushed using existing plant to provide recycled concrete aggregate (RCA) of physical properties that satisfy the current BS882 requirements. The density of both fine and coarse RC...

| description | The results for the aggregate characteristics showed that plain as well as reinforced demolished concrete debris can be crushed using existing plant to provide recycled concrete aggregate (RCA) of physical properties that satisfy the current BS882 requirements. The density of both fine and coarse RCA was found to be lower than that of natural aggregate and water absorption was 3 to 6 times higher. The test results also indicated that up to 30% coarse or 20% fine RCA had no effect on the strength of concrete, but thereafter there was a gradual reduction in strength with increase in RCA content. Studies of concrete durability showed similar peformance for RCA and natural aggregate concrete mixes of equivalent strength. (Original abstract - amended) |
